DF3DZ-2P-2H(75) Equivalent & Substitute Parts

Part Overview

The DF3DZ-2P-2H(75) is a surface mount, right-angle rectangular connector header manufactured by Hirose Electric Co Ltd. This component is a shrouded 4-wall header with 2 positions at 0.079" (2.00mm) pitch, designed for board-to-board or cable connections with solder termination and push-pull fastening. The part is discontinued at DiGi Electronics, making identification of suitable substitutes necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

The DF3EA-2P-2H(21) qualifies as a direct substitute for the DF3DZ-2P-2H(75) based on the following critical parameters:

• Connector Type & Configuration: Both are header connectors with identical male pin contact type, 2-position configuration, and 0.079" (2.00mm) mating pitch
• Mechanical Compatibility: Both feature surface mount, right-angle mounting with shrouded 4-wall design and identical insulation height of 0.220" (5.60mm)
• Electrical & Thermal Specifications: Both operate across -55°C ~ 105°C temperature range with matching material composition (brass contacts, polyamide/nylon insulation)
• Compliance & Safety: Both maintain UL94 V-0 flammability rating, MSL 1 classification, and RoHS compliance
• Termination & Fastening: Both use solder termination with push-pull fastening mechanism

The primary distinction is product status: DF3EA-2P-2H(21) is active with high inventory availability, whereas DF3DZ-2P-2H(75) is discontinued.

Parameter Comparison

Engineering Selection Recommendations

The DF3EA-2P-2H(21) is the appropriate substitute for the DF3DZ-2P-2H(75) based on product lifecycle and compliance status. The discontinued DF3DZ-2P-2H(75) should be replaced with the active DF3EA-2P-2H(21) for new designs and ongoing production support. Both parts maintain identical electrical, mechanical, and thermal specifications within the DF3 series, ensuring functional equivalence. The DF3EA-2P-2H(21) carries ROHS3 compliance, representing current regulatory alignment. Packaging format differs (Tape & Reel for the substitute), which may require adjustment to procurement and assembly workflows but does not affect component performance or compatibility.

Frequently Asked Questions (FAQ)

Q: Are DF3DZ-2P-2H(75) and DF3EA-2P-2H(21) mechanically interchangeable?

A: Yes. Both connectors share identical mounting type (surface mount, right angle), shrouding configuration (4-wall), insulation height (0.220"), and contact pitch (0.079"). They are mechanically interchangeable on PCB layouts.

Q: Do these parts have the same electrical ratings?

A: Both operate across -55°C ~ 105°C and maintain UL94 V-0 flammability rating. The DF3DZ-2P-2H(75) specifies 3A current rating; the DF3EA-2P-2H(21) current rating varies by wire gauge. Verify wire gauge requirements for your application.

Q: What is the difference in packaging?

A: The DF3DZ-2P-2H(75) packaging is not specified. The DF3EA-2P-2H(21) is supplied in Tape & Reel (TR) format, standard for automated assembly processes. This affects procurement quantity minimums and handling procedures but not component function.

Q: Why is DF3DZ-2P-2H(75) discontinued?

A: Product discontinuation is a manufacturer lifecycle decision. The DF3EA-2P-2H(21) remains active within the same DF3 series and provides full functional equivalence.

Q: Are there compliance differences between these parts?

A: Both are RoHS compliant. The DF3EA-2P-2H(21) carries ROHS3 compliance, reflecting current regulatory requirements. Both maintain MSL 1 (Unlimited) moisture sensitivity classification.
